| 摘 要： | 测定了典型西太湖入湖河口区湖滨带中表层沉积物的有机质、总氮、总磷的含量,平均含量分别为2.417%、1.049mg/g、0.402mg/g,其分布都是沿湖滨带水向辐射带、水位变幅带、陆向辐射带呈逐渐增大趋势。底泥中C/N值为12.4。底泥中有机质及营养盐来源于湖中藻类和高等水生植物。利用有机指数和有机氮评价表层沉积物,整个区域属于尚清洁范畴。

| Abstract: | Organic matter, total nitrogen and total phosphorus in the sediments of aquatic-terrestrial ecotone in Taihu Lake were determined, with average concentration of 2.417%, 1.049mg/g and 0.402mg/g respectively at surface layer, and the distribution taking on a gradually growing trend along water area, water transition area as well as terrene and terrestrial area. The C/N ratio in the Lake sediment was 12.4. Organic matter and nutrient were from alga and aquatic plant in Lake. By evaluating the surface layer sediments with organic index and organic nitrogen, it was showed that the Lake was in the state of less cleanness. |
